Abstract
An air purification assembly (10) that is adapted to be used in combination with a vehicle incorporating a heating, ventilation and air conditioning (HVAC) system (100). The assembly (10) consists of three elements: an electrostatic stabilizing filter (12), a membrane filter (32) and an electronic ionizer (40). The three assemblies (12, 32, 40) when operating in combination with the HVAC system (100) substantially absorb unpleasant odors, smoke, dust, pollen, mold spores, pet dander and particulate matter produced by a vehicle exhaust emissions.
Claims15
An air purification assembly that operates in combination with a vehicle heating, ventilation and air conditioning (HVAC) system, which comprises a return air duct, an evaporator coil, an evaporator blower and a fresh air duct, said air purification assembly comprising:
- (a) an electrostatic stabilizing filter having an inner side and an outer side, wherein the outer side is attached, by an attachment means, to a vehicle structure which is selected to allow the inner side to be positioned across the return air duct,
- (b) a membrane filter having an inner side and an outer side, wherein the inner side is attached, by an attachment means, against the outer side of said electrostatic stabilization filter,
- (c) an electronic ionizer attached, by an attachment means, to a vehicle structure which is selected to allow said ionizer to be positioned in close proximity to the air return duct and to be connected to a keyed-ON 12-volt source, which is connected to a vehicle battery, wherein when the keyed-ON 12-volt source is turned ON and the HVAC system is turned ON and placed in a re-circulation mode, the air purification assembly becomes operational, at which time air from the fresh air duct passes through said air purification assembly, is applied through the return air duct and back into the fresh air duct to continuously re-circulate purified air through the vehicle passenger compartment.
A process for installing an air purification assembly in a vehicle, wherein said assembly comprises an electrostatic stabilization filter, a membrane filter and an electronic ionizer, and wherein said vehicle comprises a battery, a keyed-ON 12-volt source, a glovebox, an under dash panel, and a heating, ventilation and air conditioning system having a return air duct, a fresh air duct and which operates in an air recirculation mode, said process comprising the following steps:
- (a) disconnect the vehicle battery,
- (b) remove the glovebox and/or the under dash panel to access the return air duct,
- (d) remove said electrostatic stabilization filter and said membrane filter from their respective packages,
- (d) attach said electrostatic stabilization filter, by an attachment means, to a vehicle structure which allows said electrostatic stabilization filter to be positioned in close proximity to the return air duct,
- (e) attach said membrane filter, by an attachment means, which allows said membrane filter to be positioned against said electrostatic stabilization filter,
- (f) attach said electronic ionizer, by an attachment means, to the vehicle structure which allows said ionizer to be positioned adjacent the return air duct,
- (g) connect said electronic ionizer to the keyed-on 12-volt source and to a vehicle ground,
- (h) reconnect the vehicle battery, turn vehicle ignition switch to ON and set the air conditioning system to the air recirculation mode to verify that said air purification assembly is functioning, and
- (i) replace the glovebox and/or the under dash panel.
